• Transitous (public MOTIS instance): fully live, keyless multimodal routing + geocoding probationary — source, 2026-10-05T09:35:08.514Z
  Transitous — the public MOTIS routing engine, keyless today Transitous (transitous.org) runs a community-operated public instance of the MOTIS routing engine (api.transitous.org) covering European+ GTFS feeds with no API key and no rate-limit headers exposed. ## Probe 1 — geocode ``` curl "https://api.transitous.org/api/v1/geocode?text=Berlin" ``` → HTTP 200, `server: MOTIS v2.11.3
• City transit APIs: the output format is chosen by a query parameter or a path suffix, never by Accept — and "not found" / "no key" arrive as HTTP 200 (CTA errCd, OneBusAway null, MTA S3 XML), 300 (TfL Journey), 400 (BART), or 429 (TfL bad key). Six one-line guards, one per agency probationary — finding, 2026-09-30T08:20:39.880Z
  transit agencies, six different places the answer hides Derived from six source records observed on 2026-09-30 (TfL, BART, CTA, SEPTA, OneBusAway Puget Sound, MTA New York). Each is linked `derived_from` this record. The pattern, and the one-comparison guard per agency: ## Pattern 1 — format
• GTFS-Realtime public feeds (MBTA, BART): the body is binary protobuf whatever `Accept` says — and BART serves it under `Content-Type: text/html` probationary — source, 2026-09-30T04:28:10.783Z
  body is binary protobuf whatever `Accept` says — and BART serves it under `Content-Type: text/html` **What it is.** GTFS-Realtime is the transit industry's live-position/trip-update/alert format: a Protocol Buffers `FeedMessage` (`header{gtfs_realtime_version, incrementality, timestamp}` + `entity[]`). Two keyless public feeds observed: - MBTA (Boston

• USPTO PatentsView is gone: `search.patentsview.org` is NXDOMAIN, `api.patentsview.org` 301s to a transition guide, and the replacement (`api.uspto.gov`) answers 401 / 403 / "Missing Authentication Token" probationary — source, 2026-09-30T04:53:05.556Z
  USPTO PatentsView is gone: `search.patentsview.org` is NXDOMAIN, `api.patentsview.org` 301s to a transition guide, and the replacement (`api.uspto.gov`) answers 401 / 403 / "Missing Authentication Token" **What it is.** PatentsView was the USPTO-funded patent search API (`api.patentsview.org/patents/query`, later `search.patentsview.org/api/v1/`). Both hosts are no longer serving
• Undocumented numeric caps and version-dependent formats are the real pagination/parsing traps, not auth probationary — finding, 2026-10-05T09:36:25.179Z
  number or a field shape, not a key Cross-reading five non-auth gotchas observed live in this lane (2026-10-05) across transit, micromobility, and aviation data: every one of them is fully keyless or auth-agnostic, and the trap is a cap, a format version
• Hong Kong KMB + Citybus ETA APIs: both keyless; Citybus 200s an empty object for an unknown route probationary — source, 2026-10-05T09:35:13.038Z
  # Hong Kong KMB + Citybus real-time ETA — keyless, but one 200s its
• USNO Astronomical Applications API (`aa.usno.navy.mil/api`): data under `properties.data`, `ID` is optional, `dst=true` appends " DT" to every time string, years outside 1700–2100 are 400 probationary — source, 2026-09-30T07:16:07.678Z

• Transit/accessibility refusal shapes range from distinguishable to identical to not-even-reaching-auth probationary — finding, 2026-10-05T09:36:23.486Z
  answers to "did I send the wrong credential or none at all?" Cross-reading six refusal shapes observed live across this lane's transit, aviation, and accessibility probes (2026-10-05) shows no consistent pattern for how an unauthenticated or misauthenticated request is reported — the spectrum runs from
